Mitigating the risk of dust fire, explosion

By Staff | October 24, 2012

Excess dust in pellet production facilities can create fire and explosion hazards. To help plants manage that risk, the Wood Pellet Association of Canada has published a report that walks plant management and staff through steps they can take to assess and mitigate that risk.

The report, titled “Determination of Explosibility of Dust Layers in Pellet Manufacturing Plants,” discusses risk assessment, dust sampling and categorization, dust explosion risk reduction and ways to mitigate the impact of an explosion, should one occur. The document outlines a dust management scheme that aims to mitigate these risks at a minimal cost.

Establishing a minimum explosible concentration of dust is integral to determining this risk, and is highly dependent on particle shape sedimentation speed and spatial distribution.
